Benefits of technology

[0005]It is an object of embodiments of the present invention to provide devices, systems, and methods for an accurate determination of position of actuated objects (e.g. motor actuated). It is an advantage of embodiments of the present invention that miscounting errors can be reduced or even excluded.

Problems solved by technology

This could result in missing or extra transitions (depending on the way of processing of the output(s)) during the activation phase (following the deactivation phase) and this in turn leads to miscounting.
Miscounting has been felt a long-standing problem in determining the position of motor-driven objects by means of magnetic field sensors to which a rotating magnetic field is applied.
Few attempts were made setting the initial output, however, such systems need extra hardware and complicated processing.

Embodiment Construction

[0037]The present invention will be described with respect to particular embodiments and with reference to certain drawings but the invention is not limited thereto but only by the claims.

[0038]The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a sequence, either temporally, spatially, in ranking or in any other manner. It is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein.

[0039]It is to be noticed that the term “comprising”, used in the claims, should not be interpreted as being restricted to the means listed thereafter; it does not exclude other elements or steps. It is thus to be interpreted as specifying the presence of the stated features, integers, steps or components as referred to, bu...

Abstract

A position sensor for determining the position of an object, comprising at least one sensing element to transduce a time-varying external signal into an electrical signal; at least one comparator circuit adapted to perform a thresholding operation on the electrical signal being characterized by a hysteresis curve; the position sensor is adapted to provide information relating to the last crossed to store it at least while the position sensor is in an inactive mode and to restore the information to obtain a selected threshold when it is switched from inactive to active mode; and configured such that a transition in an output signal is generated by the thresholding operation if the selected threshold is crossed by the electrical signal and configured to change the selected threshold after it was crossed by the electrical signal.

Description

FIELD OF THE INVENTION[0001]The present invention relates to sensor devices, methods, and sensing systems for position determination of an actuated objects and more particularly devices, methods, and systems for position determination of movable vehicle parts by means of magnetic field sensors subject to rotating magnetic fields.BACKGROUND OF THE INVENTION[0002]Modern vehicles contain numerous adjustable and movable parts, such as car windows, seats, and electric sunroofs that rely on sensor output to accurately determine the position, direction or speed of motion of the respective movable parts. A motor-driven car window for instance is lifted to a final, closed position by comparing its actual position with the final position and determining the necessary travel distance. Moreover, it is desirable that the driving motor decelerates with the car window approaching the maximum height so as not to damage mechanical parts for fixture and guidance by overstraining them, or that the mot...
